Just for clarity, DataONE makes a distinction between Science Data and Science Metadata (SciMeta) objects. DataONE supports SciMeta standards that allow for Datasets to be embedded within. The Coordinating Node will only accept a 1 Gigabyte SciMeta object, thus bounding any Membernode's SciMeta.

2013-03-08 14:56:57 -0500 edited answer What is a Member Node?

Member Nodes are organizations that are software enabled (have installed the DataONE Member Node software) to store, manage, and provide access to digital scientific data holdings as part of the DataONE federation of repositories. Member Nodes provide descriptive metadata to DataONE Coordinating Nodes facilitating discovery and retrieval of the data records. Enabling access to data through DataONE provides users with additional tools (see the Investigator Toolkit) for data management, retrieval and analysis.

Member Nodes provide access to their own data, and may partner with other data holders to provide access to partner's data and metadata. Member Nodes may have direct connection with user communities and encompass a diversity of organizations, institutions, and capabilities. There are different tiers of partnering with DataONE as a Member Node, recognizing that different organizations have different needs and capabilities.
